SIMOTICS NEMA low voltage explosion proof motors

Siemens rugged explosion-proof motors provide reliable operation even under extreme conditions. They are UL® listed and CSA certified for gas and dust ignition environments and suitable for Class I, Groups C&D, Class II, Groups F&G, Division 1 hazardous area classifications. The XP100 ID1 drill rig duty motor is certified for Class I, Group D, Division 1 hazardous locations. Petrochemical and chemical processing, mining, pulp/paper and waste management are some of the many applications where these motors have proven their performance. 

Motors for maximum safety, efficiency, productivity

The SIMOTICS NEMA XP100 explosion proof motor is the workhorse of hazardous environments all over North America. Industries from grain handling and processing, oil and gas, mining, pulp and paper, water / wastewater, chemical processing, and more depend on this motor for safety, efficiency and long-life performance.


These motors are designed and manufactured to meet or exceed NEMA Premium® efficiency (MG1 Table 12-12) as well as the high requirements for safety and protection established by NFPA 70: National Electrical Code® (NEC). They are UL listed for different hazardous atmospheres for gas and dust protection. Their IP65 ingress protection keeps all dust out of the motors, providing reliability and safety assurance. All XP100 motors are UL certified and nameplated for VFD use. IEC Ex certification is available as an option.


The NEMA XP100 ID 1 motors are designed to provide superior operating performance and energy efficiency for oil and gas drilling applications. They're available with a wide variety of features, QuikMOD modifications and custom designs to meet specific motor needs. Standard in their design, and clearly printed on the nameplate, these NEMA Premium® efficient motors can be operated with a variable frequency drive, meeting or exceeding NEMA MG1 Part 30 and 31, and maintains its outstanding performance with a speed ratio capability of 20:1 variable torque and 4:1 constant torque.

  • Frame and end shields
    SIMOTICS NEMA XP100 and XP100 ID1 Explosion Proof motors feature cast iron frames, end shields and an easy access oversized terminal box that's provided with a neoprene gasket and includes a heavy duty ground lug and non-wicking leads that are clearly and permanently marked. These characteristics plus high strength zinc-plated hardware, epoxy paint and stainless steel nameplates provide exceptional structural integrity and resistance to rust and corrosion, making them suitable for severe duty applications in harsh environments.

    For the XP100 ID 1 motors, UL approved condensation/breather drains are included on 404T – 449T frames. Lifting eyebolts are included for motors > 75 lbs.    
  • Rotor and stator windings
    A unique offset rotor bar design provides improved efficiency, while larger bars and end rings reduce resistance for lower rotor losses. Each die-cast aluminum rotor assembly is dynamically balanced for extended bearing life and includes a high-strength carbon steel (C1045) shaft for maximum rotor performance. The stator is manufactured with premium electrical C5-grade steel laminations and copper electrical magnet wire that furthers the reduction of losses
  • Insulation
    The proprietary Class F non-hygroscopic insulation system with NEMA Class B temperature rise provides an extra margin of thermal life. The varnish system ensures maximum winding penetration to provide protection from moisture, corrosion and electrical shock. This insulation system meets or exceeds NEMA MG1 2014 Part 31 making the motors suitable for variable speed drives in constant torque (4:1) and variable torque (20:1). All windings are tested for CIV
  • Cooling System
    A non-sparking, bi-directional fan is locked and keyed to the shaft. Its low-inertia design reduces windage losses, improves airflow, reduces noise and provides dependable cooling. Cast Iron fan covers are standard for all frame sizes
  • Bearings
    Single shielded bearings are used for better bearing protection against contaminants. All XP100 motors have regreasable bearings with rugged, easy-to-access grease fittings
